Description

[0001] FITTING FOR VEHICLE SEAT AND VEHICLE SEAT [0002]

The invention relates to a fitting for a vehicle seat having the features of the preamble of claim 1, and to a vehicle seat having the features of claim 15.

DE 10 2011 010 699 A1 initiates a comprehensive fitting with indicator. The radially projecting pointer of the indicator, which is connected rotationally conjointly to the actuator of the fitting, displays the actuator and thus the angular position of the eccentric, which is then displaced by the eccentric Makes it clear whether the catches to be actuated are radially outwardly or radially inwardly, i.e. whether the fitting is locked or unlocked. Due to the internal structure of the fitting, the angular positions of the actuator and therefore the respective positions of the indicator are only slightly different between the locked and unlocked states of the fit. In particular, if the tooth ring and the toothing of the catches are "tip to tip ", and thus locking, they are not meshed engagement with each other, Each change is visually barely noticeable. Accordingly, the pointer exhibits only limited fitness as a unlocked state display of the fit.

DE 10 2008 047 901 A1 discloses an electromotively actuated fit, the lock state of which is detected by a sensor. This sensor is fastened to the fitting by the sensor clamp and, based on the angular position of the cam, detects whether the fitting of the fitting has been moved to the unlocked position. This solution requires a sensor clamp, which is disadvantageous in that it takes up additional structural space and involves additional costs and additional weight. In addition, the sensor arrangement of this type can not be easily transferred to the manually unlockable fittings.

A fitting for a vehicle seat without indicator and without sensor is disclosed by DE 10 2006 015 560 B3.

The present invention is based on the problem of providing a reliable and unambiguous unlocked state display for a manually actuatable fit that improves the fit of the type mentioned in the introduction, more particularly in terms of cost and weight. Further, the present invention is based on the problem of providing a vehicle seat having a fit of this type.

This problem is solved according to the invention by a fitting with the features specified in claim 1 and by a vehicle seat as claimed in claim 15.

The dependent claims relate to advantageous improvements which may be used separately or in combination with each other.

An adapter connected to the actuating lever is rotatably mounted on the actuator or on a clamping ring fastened to the actuator, and when the actuating lever is not driven regardless of the locked state of the fit, the adapter returns to its initial position by the return spring. And by the fact that the sensor is fastened to the adapter, only a small structural space can eliminate additional components for fastening the sensor in one section of the available fitting. In the non-actuated state, the actuation lever is always in its initial position, so that the sensor, which is kinematically coupled to the actuating lever via the adapter, always detects the lock state accurately and reliably.

By virtue of the fact that the position change of the indicator is detected and converted to an electrical output signal by the sensor connected to the fitting, even small changes in the indicator position can be reliably detected and converted to electrical or electronic signals.

The present invention is particularly easy to integrate into the fits and the catches of the fits are pulled radially inwardly by the control disk connected to the eccentric or actuator to unlock the fit so that the eccentric portion of the fit The eccentric portion of the fitting is rotated out of its initial angular position during unlocking of the fit and is locked in place by the catch of at least one of the catches in the unlocked state of the fit, It is prevented from turning. In the case of these fittings, each position of the actuator is a unique function of the locking state of the fitting.

In the case of the sheets of the second row of seats, the access to the rear seat train can be facilitated by the backrest of the front seat which is free to swivel, so that the unlocked backrest can be seated from one of the use positions And is pivoted into a pivoting free position which is not suitable for. If the actuating lever does not need to be maintained throughout the pivoting free process, the operational comfort is increased. To this end, a free-wheeling control element as known per se can be provided in the fitting. Accordingly, the fitting can assume an unlocked state even when the drive lever is in the non-driven state.

The actuator can be connected to the delivery rod by a profiled connector, the actuator can be driven by the transfer rod in the unlocking direction, and, in contrast to the unlocking direction, a degree of play in the profiled connector, By virtue of the fact that it permits limited mobility between this driver and the transmission rod, even when the actuating lever, which is operatively connected to the transmission rod and the transmission rod, is unable to rotate reversely due to the unlocked state of the fit, To be reversed to the initial position.

An adapter rotatably mounted on or fastened to a driver on a driver and returned to an initial position by a return spring when the actuator is not actuated regardless of the locked condition of the fitment is affixed to the sensor Particularly suitable. Here, it is preferable that the adapter is rotatably connected to the transmission rod and the operation lever.

The adapter and the operation lever may be integrally formed. Then, the operating lever is part of the adapter, whereby the sensor is fastened to the operating lever.

If the indicator has a profile that can be pushed axially onto the profile of the clamping ring or actuator of the actuator and thus can be formed into a rotatable connection between the indicator and the actuator, the indicator is mounted on the actuator, Can be mounted on the ring in a simple manner.

The indicator is preferably arranged axially between the fitting portion and the adapter. In this position, the indicator is protected against breakage.

Elastic and electrically conductive contacts Sensors including contact tongues and electrically conductive contact surfaces are simple structures and therefore inexpensive. In the case of an unlocking fit, the switching surface of the indicator abuts the contact surface to press the contact tongue, thereby closing the electrical circuit.

The costs and weight of the fitting can be further reduced if the sensor or at least its tongue-like portion is integral with the adapter as an insertion component.

Microswitches are particularly suitable as sensors because they are available in a wide variety of embodiments.

If the positional change of the indicator as an input signal detected by the sensor is preferably an angular change, but also if intermediate gearings are used which convert the rotational motion of the actuator into a linear motion, also movement changes are possible.

The signal conversion is preferably based on the contact between the sensor and the indicator but may also be implemented with good results using contactless, inductive, capacitive or ohmic means .

The output signal of the sensor, which is further processed by the evaluation electrical device or evaluation electronics, may be a current, a current change, a voltage, a voltage change or a combination of the above-mentioned variables. The unlocked state is advantageously displayed correctly, when the electrical circuit is disconnected. By corresponding modification of the evaluation electrical devices / electronic devices, however, it can also be provided that the locked state is displayed only when the electrical circuit is closed.

The vehicle seat with the fitting according to the invention is functionally reliable, relatively lightweight and inexpensive.

The invention will be described in more detail below on the basis of advantageous exemplary embodiments illustrated in the drawings. However, the present invention is not limited to these exemplary embodiments.

The automotive vehicle seat 1 has a seat portion 3 and a backrest 4 adjustable with respect to the inclination with respect to the seat portion 3. [ The transmission rod 7 horizontally arranged in the transition region between the seat portion 3 and the back 4 for manual release and inclination adjustment of the back 4 can be manually operated, Is rotated by the lever (5). On one side of either side of the vehicle seat 1, the transmission rod 7 engages into the fitment 10. [ On the other side, the transmission rod 7 is mounted on a rotary bearing between the seat portion 3 and the back 4. At each end of the transmission rod 7, that is, on both sides of the vehicle seat 1, in each case, one operating lever 5 is provided. In this case, a tension lug is affixed to the hook 5a of the operating lever 5. The attachment hole 5b allows the attachment of the first cable pull end for the addition of the fitting 10 or for alternative actuation. The second cable pull end can, for example, be secured to a further operating element in the region of the backrest head. The operation lever 5 illustrated in Figs. 1, 2 and 7 is driven counterclockwise for unlocking the fittting 10. Fig.

In a modification of the exemplary embodiment, only one actuating lever 5 is provided, the actuating lever being arranged on the end of the transmission rod 7 assigned to the fit 10, or on the end assigned to the rotary bearing, .

The fitting 10 has a first fitting portion 11 and a second fitting portion 12 rotatable about each other about the axis A. (Imaginary) axis A is in this case aligned with the axis of the transfer rod 7 and defines the term (here used) for the orientation of the cylindrical coordinate system. The two fitting portions 11 and 12 are respectively shown in the form of a circular disk. The two fitting portions 11, 12 are preferably made of metal, in particular steel, which can be hardened at least in the zones. A clasp ring 13 is provided to absorb the forces acting in the axial direction, i.e. to hold the fitting portions 11, 12 together in the axial direction. The cladding 13 preferably comprises a metal, in particular a steel, which is preferably not cured. The cladding 13 preferably has a substantially flat ring shape, but may also have an L-shaped profile with a cylindrical section and, in an alternative embodiment, a flat ring section on the end side.

The flanging 13 is applied to the fitting portion of one of the two fitting portions 11, 12, in this case, in the outer ring section, for example by laser welding, or by some other fastening technique known per se To a second fitting portion (12). By means of the inner ring sections arranged in a plane perpendicular to the axial direction, the class furring 13 can, if appropriate, prevent the relative movement of the two fitting portions 11, 12 by the interposition of the slide ring But engages on the first fitting portion 11 in its radially outer edge region. In addition, the inner surfaces (facing each other) of the two fitting portions 11, 12 are protected against entry of foreign matter and contaminants and against breakage.

The fitting portion 11 or 12 fixedly connected to the class fibril 13 and the class fibril claspes the other fitting portion of the two fitting portions 11 and 12 thereby forming a class It is movable relative to the former and the former fitting part. In a structural aspect, the two fitting portions 11, 12 thus form a plate-like unit together (with the class furring 13).

By the fitting of the fitting 10, the first fitting part 11 is fixedly connected to the structure of, for example, the backrest 4, that is, fixed to the backrest. The second fitting part 12 is fixedly connected to the seat part adapter 3a, which is fixedly screwed onto the structure of the seat part 3. [ The second fitting portion 12 is thus fixed relative to the seat portion. However, the assignments of the fitting portions 11, 12 may be interchanged, that is, the first fitting portion 11 may then be fixed relative to the seat portion, and the second fitting portion 12 may be fixed . The fit 10 is placed in a force flow between the seat back 3 and the seat back 4.

The fitting 10 is in the form of a latching fitting in which the first fitting part 11 and the second fitting part 12 can be locked to each other, as described, for example, in DE 10 2006 015 560 B3 , The contents of which are expressly incorporated herein by reference.

The second fitting portion 12 has guide segments 14 (in this case, there are four), which, through the paired straight guide surfaces, in each case radially sideways Thereby guiding one catch 16 to the other. The catches 16 (in this case, a total of four in this case) are arranged in relation to one another in a defined structural space between the two fitting portions 11, 12 (in this case, in each case by 90 degrees) Offset. The catches 16 are provided with a toothed portion on the radially outer end of the catches which can be engaged with the toothed ring 17 of the first fitting portion 11 in the form of an internal gear do. When the tooth type ring 17 and the catches 16 interact, the fitting 10 is locked.

The first fitting portion 11 is arranged in a depression of the second fitting portion 12 and is radially engaged with the outer side by the second fitting portion so that the two fitting portions 11, 12) support each other. Here, the radially outer edge region of the first fitting portion 11 defines a radially outer edge region of the guide segments 14 and the second fitting portion 12 (acting to support the first fitting portion 11) Shaped ring 17 in the radial direction. The first fitting portion 11 abuts against these guide segments 14 which are located closest to the direction of the load after the deformation, And the guide segments have a curved surface corresponding (concentrically) in the direction of the tooth type ring 17. This increases the strength of the fitting 10.

At the center of the fitting 10 there is arranged a drive 21 composed, for example, of plastic, which is mounted on one or more of the two fitting portions 11, 12, in this case a first fitting portion 11, more specifically at its central opening. The driver 21 has a profiled hole 21a designed to interact with the transfer rod 7 in the axial direction. The cylindrical basic shape of the profiled hole 21a is interrupted by webs 21s pointing four radially inward sides which are oriented axially and uniformly around the profiled hole 21a . The transferring rod 7 has a counterpart profile with four grooves 7n uniformly distributed around the transferring rod 7. Each of the four webs 21s is held in abutment with each groove 7n in the circumferential direction and in the driving direction of the operating lever 5, i.e. in the unlocking direction of the fitting 10. Thus, the rotational motion of the transfer rod 7 is transmitted to the actuator 21. In order to allow for the purpose of tolerance compensation and to allow the drive lever 5 to rotate back to its initial position even if the fitting is unlocked, A certain degree of clearance S is provided between the grooves 7n and the webs 21s in counter direction. For this purpose, the webs 21s have a smaller width in the circumferential direction than the grooves 7n.

On one end of the actuator 21, in this case on the end arranged in the region of the second fitting part 12, a locking ring 24 is provided, which in this case is made of plastic, And fastened to the actuator 21 by ultrasonic welding.

The eccentric 27 is rotationally conjointly seated on the actuator 21 and this eccentric element is arranged in a defined space defined between the fitting portions 11 and 12. One or two spiral springs nested one inside the spring arrangement 35, for example one of the two fitting portions 11, 12, in this case the second fitting portion 12 and is externally supported in this case. The spring arrangement 35 imposes a load on the eccentric device 27, in this case by means of the spring arrangement which is rotationally engaged on the driver 21 internally. A spring arrangement 35 of this type is described, for example, in DE 10 2005 046 807 B3, the contents of which are expressly incorporated herein by reference. The eccentric device 27 which is subjected to a load by the spring arrangement 35 operates on the catches 16 which are moveable in the radial direction and is adapted to be meshed with the tooth type ring 17, Lt; RTI ID = 0.0 > radially outwardly < / RTI >

The control disc 36 is arranged axially between the catches 16 and the first fitting portion 11 in the structural space defined between the fitting portions 11 and 12 and in this case, And is seated rotationally on the planting machine (27). The control disc 36 has control tracks (in this case, there are four), which in each case interact with the lugs 38 of each catch 16. In this case, the lugs 38 project axially from the associated catches 16 together. The control disk 36 is rotated at an angle of several degrees relative to the actuator 21 (the eccentric 27 and the control disk 36 driven by the actuator) against the force of the spring arrangement 35. [ The fittings 10 are unlocked and the two fitting portions 11 and 12 are fitted to the shaft A in the radially inward direction, i.e. pulling the catches 16 out of the tooth type ring 17, And are rotatable relative to each other about the center. Now, the backrest 4 is pivotable about the axis A so as to be adjusted in terms of its inclination, i.e. to assume a different position of use.

In the unlocked state of the fitting 10, the catches 16, which are pulled radially inward and laterally, protrude into one or more radially outer chambers of the eccentric 27 which abut against at least one of the catches 16 Thereby preventing the backward rotation of the eccentric mechanism 27 by the cam. Thus, the actuator 21, which is rotationally coupled to the eccentric 27, can not also be reversed to its initial position.

In the case of two-door cars, or in the case of the sheets in the second row of sheets, access to the rear seat train can be facilitated by freely pivoting the seat back 4, Is pivoted from one of the forward use positions into the free swivel position, at which point the seat is not fit to sit on. If the actuating lever 5 (or an additional actuating element connected thereto through the attachment hole 5b) does not need to be maintained throughout the entire turning free process and nevertheless the fittings only lock in the free turning position, Operational comfort is increased. For this purpose, optionally an annular swivel free control element, for example as described in DE 10 2006 015 560 B3, is provided between the control disc 36 and the first fitting part 11 around the axis A , The content of which is expressly incorporated herein by reference.

The fitting 10, the transferring rod 7 and the actuating lever 5 are parts of a fitting system which also preferably includes a spiral back compensating spring 41, . The radially outer first spring end of the backrest compensating spring 41 is supported on the backing lug 4a of the backrest 4. The radially inner second spring end of the backrest compensating spring 41 is supported on a spring adapter 3b which is attached to the seat portion 3. [ The backrest compensating spring 41 compensates for the gravitational load of the occupant leaning against the back 4 (this back is inclined backward in the vertical direction at the use position) and the back 4 .

The transmission rod 7 is arranged between the fitting 10 on the first side of the vehicle seat and the rotary bearing (not shown in the figures) on the second side of the vehicle seat. In a modification of the exemplary embodiment, the rotating bearing is replaced by a second fit 10. The transfer rods 7 are arranged between the two fits 10 and engage into them at both sides.

The fastening ring 24 of the fitting 10 has a plurality of different functional areas, of which four are present in this case. Immediately abutting axially on the second fitting portion 12, the fastening ring 24 has an outer profile 24a (in this case, a square with rounded corners) formed in a surrounding fashion on a radially projecting material section, Respectively. On the free end turning back the second fitting portion 12, the fastening ring 24 also has a radially projecting collar 24b. Radially, in the collar 24b, an inner profile 24c, e.g., a surrounding undulation or spline profile is formed. The inner profile 24c is an interface for possible additional attachment portions, but in this case, it is not functional. In the radially inward direction, the hollow fastening ring 24 is provided with a passage 24d into which a driver 21 is partly inserted, through which a drive rod 21, surrounded by a driver 21, (7) runs in a relatively movable manner.

An outer profile 24a is provided on the first side of the vehicle seat for rotationally interacting with an indicator 51 acting as a signal transducer. The indicator 51 is a ring with a radially projecting pointer 51z, and on its radially outer end, the switching surface 51s is axially curved. The ring of the indicator 51 has a profile 51a on its inner side which fits into the outer profile 24a and preferably interacts positively in a locking manner. The indicator 51 represents the respective position of the actuator 21 and thus of the eccentric 27 so that the catches 16 to be loaded by the eccentric 27 are radially outwardly Or whether it is radially inwardly, i.e. whether the fit 10 is locked or unlocked.

A channel 24g is formed axially between the outer profile 24a and the collar 24b on the clamping ring 24 and is for example 1 mm deep with respect to the collar 24b. The collar 24b is a constituent part of the axially operating clip connection between the locking ring 24 and an additional component that is clipped on. Due to the channel 24g, the collar 24b can be engaged rearward to create a clip connection. The clip-on component having geometric shapes that interact with the collar 24b is an adapter 55, in this case preferably formed of plastic. The adapter 55 has an annular basic geometric shape with a central opening 55d through which the transmission rod 7 is connected in an axial direction And is guided in a movable manner. To this end, the central opening 55d has a profiled shape with four profile webs 55s, which are arranged in the direction of the conveying rod 7 for conjoint rotation in both rotational directions Create a connection to the profile. The adapter 55 additionally has geometric shapes for a fixed connection to the actuating lever 5 and for axially securing the locking ring 24 to the fitting 10.

The plurality of first clip hooks 55a of the adapter 55 (axially oriented toward the fitting 10) each have a hook lug pointing radially inwards, Engage through the hook lugs behind the collar 24b of the collar 24b and fasten the adapter 55 to the fastening ring 24 in the axial direction. By doing so, the adapter 55 is mounted on the fastening ring 24 in a rotatable but axially fixed manner.

The adapter 55 is rotatably connected to the operating lever 5 on the side of the back of the fitting 10. To this end, the adapter 55 has six circumferential centering arms 55b which point axially away from the fitting 10. [ In addition, in the intermediate spaces between the individual centering arms 55b, six second clip hooks 55c offset slightly radially inwardly relative to the centering arms 55b are provided. On the operating lever 5 in the axial direction, six clip hooks 5c are provided, which engage in intermediate spaces between the two centering arms 55b in each case, and the second clip hooks 55c. Alternatively, the operating lever 5 and the adapter 55 may be formed in one piece with each other.

A return spring 71 operating between the spring adapter 3b of the seat portion adapter 3a and the adapter 55 applies a torque on the adapter 55 which is fastened to the adapter 55 and the adapter A preliminary load is applied to the operating lever 5 in the direction of its non-driving initial position. As a result and due to the clearance S during the profile connection between the delivery rod 7 and the actuator 21, the adapter 55 and the actuating lever 5 fastened to the adapter are not driven by the user , And then reverses to its initial position.

On its outer circumferential surface, the adapter 55 has a sensor 61 which detects a change in the position of the indicator 51 and converts it into an external electrical signal. In this case, the sensor 61 comprises an electrically conductive contact tongue 61a (resiliently connected to the adapter 55) and an electrically conductive contact surface 61b (in particular fixedly connected to the adapter 55) And the contact tongues and the contact surface are part of an electrical circuit. When the contact tongue 61a abuts against the contact surface 61b and is supported, the electric circuit is closed. To this end, the contact tongue 61a and the contact surface 61b are connected to an electrical plug connector (not shown in the drawings), in particular in the respective cases, in particular via an electrically insulated cable. The plug connector may be attached to the electromagnetic display element (provided on the vehicle seat) of the unlocked display or, for example, in a dashboard, by vehicle electrics or electronic (and thus by disruption ) To activate the unlocked state display).

The indicator 51 is arranged axially between the second fitting portion 12 on one side and the adapter 55 and the actuating lever 5 on the other side. The switching surface 51s of the indicator 51 interacts with the contact tongue portion 61a of the sensor 61. [ If the switching surface 51s is located within the region of the contact tongue 61a, the switching surface 51s abuts the contact surface 61b and presses the contact tongue 61a radially inward and laterally, Closing. When the switching surface 51s moves away from the contact tongue 61a, the contact tongue 61a is deflected radially outward and moves away from the contact surface 61b. Thereafter, the electric circuit is disconnected.

The angular position of the pointer 51z of the indicator 51 with respect to the second fitting portion 12 fixed to the seat portion and thus the switching surface 51s depends on the locking state of the fit 10 do. In the initial position illustrated in FIG. 8, the fitting 10 is in a locked state. The switching surface 51s lies on the sensor 61 in the radial direction and abuts the contact surface 61b to press the contact tongue 61a. The electrical circuit is closed.

9 shows the actuated actuation lever 5 which is deflected from its initial position by means of an adapter 55 which is rotationally connected to the lever so that the fastening ring 24 and consequently the actuator 21 ). As a result, the fitting 10 is unlocked, and the back 4 can be pivoted. The rotation of the adapter 55 affects the rotation of the sensor 61 and also the indicator 51 fastened thereto. In addition, the switching surface 51s drives the sensor 61 by the contact tongue portion pressed against the contact surface 61b. The electrical circuit remains closed.

When the biased operating lever is released, the spring arrangement 35 contained in the fitting 10 rotates the eccentric 27 back with the actuator 21, thereby causing the fitting 10 ) On the catch 16 to pass. The actuator 21 rotates its locking ring 24 and thus the indicator 51 backwards. In addition, the locking ring 24 rotates the adapter 55, whereby the biased operating lever 5 returns to its initial position. In addition, the switching surface 51s continues to drive the sensor 61 by the contact tongues that are pressed against the contact surface 61b. The electrical circuit remains closed.

If the fitting 10 (as illustrated in Fig. 10) is not locked, for example because the catch 16 and tooth type ring 17 are in the "tooth on tooth" Catches 16 pulled sideways prevent the eccentric 27 and the driver 21, which is rotationally connected thereto, from rotating backward. The adapter 55 together with the sensor 61 is returned to the return spring 71 while the indicator 51 connected to the fastening ring 24 of the driver 21 does not rotate backward or completely rotate backward, And the clearance (S). Thereby, the switching surface 51s moves away from the contact tongue 61a, which is disconnected from the contact surface 61b such that the electrical circuit is disconnected and the display in the unlocked state described above is driven Moves away by spring action. Accordingly, the user identifies that it has not yet reached the initial position, i.e., that the fitting 10 is not yet locked, and that handling is still required to achieve accurate locking. Position can be removed by a minimum turning movement (approximately 1 [deg.]) Of the back 4.

In a modification of the exemplary embodiment, the backrest 4 is articulatedly connected to the seat portion 3 on both sides of the vehicle seat 1 by a single fitting 10 in each case. In this case, the second fitting 10 may also have corresponding means, including an indicator 51 and a sensor 61, to sense the unlocked condition. Thereafter, the electrical signals of the two sensing means are evaluated by an evaluation electrical device or an electronic device. If the OR combination is used, the unlocked state of the back 4 is displayed, for example, whether one of the two fits 10 is unlocked.

In a further modification of the exemplary embodiment, the adapter 55 is formed with additional functions of an abutment module as is known, for example, from DE 10 2010 025 112 A1. To this end, the central opening 55d of the adapter 55 has a profiled shape that forms a rotationally coupled connection in the profile of the transfer rod 7. [ In this way, the adapter 55 is operatively connected to the actuating lever 5 on one side and to the transmission rod 7 on the other side. In at least one rotational direction of the hand lever 5, the transferring rod is supported by the abutment geometric shapes of the adapter 55 interacting with the abutting geometric shape of one of the fitting portions 11 or 12 of the fitting portions And abuts against one of the fitting portions (11 or 12) of the fitting portions. As a result, the internal components of the fitting are protected against abused forces.

In the above exemplary embodiments, a signal is output every time the fittting 10 is unlocked and the drive lever 5 is deactivated due to the disconnected electrical circuit. However, in a further modification of the exemplary embodiments, it is also possible for the signal to be output whenever the fit 10 is unlocked, regardless of each position of the actuating lever 5. To this end, idle travel has to be provided in the circumferential direction between the actuating lever 5 and the adapter 55 and / or between the adapter 55 and the clamping ring 24.

The features disclosed in the above specification, the claims and the drawings will be important in both and in combination for realization in various embodiments of the invention.
